SASH LOCK AND LIFT SPECIFICATION forming part of Letters Patent No. 765,172, dated July 19, 1904.

Application filed November 13, 1903. Serial No. 181,084. (No model.)

Figure 1 is a view showing the sash lockand lift properly applied to a window and the window-sash locked. Fig. 2 is a View showinga `portion ofa window-sill, also a portion ofthe window-sash, showing my improved Alock properly attached and the lower sash elevated. Fig. 3 is a top View of the socket. Fig. 4f is a front view of the socket, showing the lockbar locked thereon and illustrating the lockholding lever extension in section. Fig. 5 is a vertical section showing the window-sash locked.

The present invention has relation to sash lock and lift; and it consists in the novel construction hereinafter described, and particularly pointed out in the claims.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

In the accompanying drawings, 1 represents a window-frame, which is of the ordinary construction, and 2 represents the sash, which of course is adapted to move up and down in the usual manner and to which sash is attached the glass.

To the bottom member of the sash-frame 2 is attached the combined lift and lock bar 3, the upper end of which is provided with the lift-flange 4, which lift-Hange is substantially of the form shown and is preferably formed integral with the bar. The bottom of the lower end of the bar 3 is provided with the angle portion 5, which angle portion extends forward and at an angle to the vertical face of the lower sash-rail. The front or forward face of the angle portion 5 is provided with the lug 6, the upper portion of which is provided with a smooth flat face 7.

The socket-plate 8 is substantially of the form shown and is secured to the window-sill 9 and placed in such a position that its rear edge will come in a vertical line with the sashshoulder 10, formed upon the sill 9.

The socket-plate 8 is provided with the forward extension 11, which forward extension is provided with the ridges 12 and 13,located upon lopposite sides of the extension 11, the ridge 13 being somewhat higher than the ridge 12, said ridges being formed of different heights for the purpose hereinafter described.

The socket-plate 8 is provided with the openings 14 and 15, the opening 15 entering to and communicating with the opening 14. rlhe opening 14 is for the purpose of receiving the angle extension 5, the opening 15 being for the purpose of receiving the lug 6.

To the socket-plate 8 is pivotally attached the lock-bar 16, which lock-bar is formed of such a length thatwhenit is turned upon its pivotal point, so as to become parallel with the extension 1l, its inner end will come over the top of the lug 6 when the parts are in the position ,illustrated in Fig. 5, thereby locking the sash to the window-sill. The lock-bar 16 is provided at its outer end with the downward-extending portion 17, which downward-extending portion is so formed and located that its under edge will press against theridge 12 as it passes said ridge.

The extension 11 is slightly curved upward, so that its outer end will clear the windowsill, thereby allowing the extension to be sprung downward sufficient to allow the lockbar to pass the ridge 12, the ridge 13, however, being formed of sufiicient height to prevent further rotation of the lock-bar, thereby holding the lock-bar in proper position to lock the sash and atv the same time prevent any accidental displacement of the lock-bar. It will be understood that the extension should have slight spring within itself, as the only object is to allow the same to be sprung downward but a trie, so that the downward-extending portion of the lock-bar 17 will pass the lowermost ridge 12.

1n order that the extension 11 may be sprung downward at the time the downwardextended portion 17 of the lock-bar 16 passes the ridge 12, the outer end of the extension IOO ll is curved upward and its bottom or under side removed from the bottom of' the windowsill, as illustrated in Fig. 5, and of course the extension 1l should be formed so that its normal position will be that shown in Fig. 5, and when released after being pressed downward it will resume its natural position. In order to accomplished this result, the extension 1l should be formed of' suitable spring material.

rlhe socket-plate is provided with the beveled back portion 18, which beveled back portion is provided with the inclined face adapted to' engage the angled portion of the bar 3,

thereby drawing the sash-rail toward the shoulder lO of' the window-sill 9.

It will be understood that by my peculiar arrangement the sash-frame is held snugly in position when locked, thereby preventing any rattling or movement ot' the sash and at the same time securely locking the sash in a closed position.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a sash lock and lif't, a bar secured to the rail of' a sash, said bar provided at its lower portion with an angled part, said angle part provided with a lug, a socket-plate secured to a window-sill provided with openings, one of' said openings adapted to receive the angle portion of the bar, and the other adapted to receive the lug, a lock-bar pivoted to the socket-plate and adapted to lock the bar in the socket-plate, substantially as and for the purpose specified.

2. As an improved article of' manufacture, a sash lock and lift consisting of' a socketplate, said socket-plate provided with a spring extension provided with ribs, a lock-bar pivoted to the socket-plate and adapted to be engaged at its free end between the ribs of the spring extension, and a bar detachable from the socket-plate, substantially as and for the purpose specified.

3. A socket-plate provided with openings, a beveled part located adjacent to the larger opening, a bar provided with a lower angle portion, said bar provided with a lug at its lower end, and a lifting-flange at its upper end, and a lock-bar pivoted to the socketplate, substantially as and for the purpose specified.

4. In a sash lock and lift, a bar or plate held in fixed position with reference to the windowsash, said bar provided with a lower angled extension, said angle extension inclined forward at its lower end from the face of the sashrail, land said lower angled extension provided with a lug, asoclet-plate provided with a beveled rear portion and a lock-bar pivoted to the socket-plate, and means for holding said lockbar in fixed position to lock the bar to the socket-plate, substantially as and for the purpose specified.

5. ln a sash lock and lift, a bar secured to the sash-rail of' the sash, a socket-plate provided with openings to receive the lower portion of' the bar, said socket-plate provided with a spring' extension, and a lock-bar adapted to be engaged by the spring extension, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of' two witnesses.
